Zcash developers have proposed reducing the target block time from 25 seconds to 20 seconds, just days after the NU7 upgrade activated on Nov. 6. The draft ZIP has been submitted to the community forum for inclusion in the next round of community voting and is being considered for implementation in the upcoming NU7.1 network upgrade. The proposal aims to shorten transaction confirmation times and improve user experience in scenarios such as POS payments, exchange deposits, and cross-chain swaps. According to the draft, the change will not increase the network's total daily private transaction capacity and keeps the existing ZEC issuance schedule unchanged. The NU7 upgrade went live on Nov. 6, cutting block time from 75 seconds to 25 seconds and introducing network sustainability mechanisms.
